I am an assistant professor at the Penn State University, with a joint appointment between the School of International Affairs and Department of Civil and Environmental Engineering. I serve as the associate director for the Initiative for Sustainable Energy Policy in the School of Advanced International Studies at Johns Hopkins University, and the associate director for Penn State's Center for Climate Risk Management. My research aims to inform energy policy in both emerging markets and advanced economies to align their decarbonization efforts with local environmental and socioeconomic concerns, such as air pollution, public health, water conservation, and economic development. I use a variety of modeling methods to generate policy-relevant information, including atmospheric chemistry and transport model (e.g. WRF-Chem), integrated assessment model (e.g. GCAM, GAINS, RICE), as well as optimization model. I received my PhD degree in Science, Technology and Environmental Policy from the Woodrow Wilson School of Public and International Affairs, Princeton University, and my bachelors degree in Environmental Science from Peking University, China. Before coming to Penn State, I was a Giorgio Ruffolo Post-Doctoral Fellow and a Research Associate with the Belfer Center for Science and International affairs at the J.F. Kennedy School of Government, Harvard University,
